1. Systems affected:
All versions of KDE up to and including KDE 3.0.2
2. Overview:
KDE's SSL implementation fails to check the basic constraints on
certificates and as a result may accept certificates as valid that were signed
by an issuer who was not authorized to do so.
3. Impact:
Users of Konqueror and other SSL enabled KDE software may fall victim
to a malicious man-in-the-middle attack without noticing. In such case the
user will be under the impression that there is a secure connection with a
trusted site while in fact a different site has been connected to.
4. Solution:
Upgrade kdelibs to KDE 3.0.3. A patch for KDE 2.2.2 is available as
well for users that are unable to upgrade to KDE 3.
5. Patch:
A patch for KDE 2.2.2 is available from
